INCORPORATION BY REFERENCE

The disclosure of Japanese Patent Application No. 2017-244932 filed onDec. 21, 2017 including the specification, drawings and abstract isincorporated herein by reference in its entirety.

BACKGROUND 1. Technical Field

The present disclosure relates to a management system of substituteparking service, a method of assisting use of the substitute parkingservice, and a non-transitory computer-readable storage medium storing amanagement program.

2. Description of Related Art

When a driver drives a vehicle to visit a certain place (such as a shop,shopping mall, or event site), for shopping, or attending or viewing anevent, for example, and finds that a parking lot at the place visited isfull, the driver may wait while driving the vehicle, in a waiting linefor parking, until a parking space in an empty state (which will becalled “empty space”) appears. Also, even when the driver tries to findan empty space while driving slowly in the parking lot, the driver maynot be able to easily find any empty space, and may let another vehicleparked first in a space missed by the driver. In some cases, the drivermay give up using the parking lot of the place visited, and park thevehicle in another parking lot in the vicinity of or around the placevisited. Thus, not a small number of drivers think searching for aparking lot or parking space, or waiting for appearance of an emptyspace, as a waste of time.

In the related art, there is a parking guidance navigation system thatguides a vehicle to an empty parking space when the empty space appearswhile the driver is looking for one (see, for example, Japanese PatentApplication Publication No. 2006-209429 A (JP 2006-209429 A)).

SUMMARY

According to the related art, the length of time it takes from the timewhen the empty space appears to the time when the vehicle is parked inthe space can be shortened. However, the driver has to continue to drivethe vehicle, until the empty space appears, and the driver moves thevehicle to the space and completes parking. Thus, it may be proposed touse substitute parking service that has a substitute driver park thevehicle, in place of the driver. The service user (e.g., the originaldriver who owns the vehicle) stops the vehicle at a delivery location.Then, the substitute driver goes to the delivery location of thevehicle, and is temporarily allowed to operate the vehicle, so as tomove the vehicle to a parking lot and park it there.

In the process of promoting and spreading the use of the substituteparking service as described above, the following problem isencountered. For example, a service provider is assumed to present aparking lot in which the vehicle is to be parked, and its position, tothe service user. In this case, even if the service user can approve ofthe parking lot and its position, it is unclear what path the substitutedriver will take when he/she drivers the vehicle to the parking lot.Thus, the service user may be concerned about a possible waste of fuelor electric power, and may not conclude an agreement on the use of theservice, or may be discouraged from repeatedly using the service.

This disclosure provides a management system of substitute parkingservice which can give a sense of reassurance about the substituteparking service, to a service user, a method of assisting the use of thesubstitute parking service, and programs.

The disclosure provides substitute parking service in which a substitutedriver parks a vehicle of a service user, in place of the service user,in which information indicating a path along which the vehicle to betraveled from a delivery location of the vehicle of the service user toa parking lot is supplied to a terminal of the service user.

A management system according to a first aspect of the disclosuremanages substitute parking service in which a substitute driver parks avehicle of a service user, in place of the service user. The managementsystem includes a processor configured to generate, based on deliverylocation information indicating a delivery location at which the vehicleis delivered to the substitute driver, and parking lot informationindicating a position of a parking lot in which the vehicle is allowedto be parked, path information indicating a path along which the vehicleto be traveled from the delivery location of the vehicle to the parkinglot, and the processor being configured to transmit the path informationto a terminal of the service user.

With the management system according to the first aspect of thedisclosure, the path information indicating the path from the deliverylocation to the parking lot is generated, and transmitted to theterminal of the service user. The service user can be informed of thepath along which the substitute driver moves the vehicle, by referringto the path displayed on the terminal, and can recognize that thesubstitute driver will not pass a path unnecessary for travel of thevehicle to the parking lot, and will not waste fuel. Thus, the serviceuser is provided with a sense of reassurance, and can easily make adecision on the use of the service. Also, where the service user hasalready concluded an agreement on the use of the service, the user canrecognize, by referring to the path, that the service will be done insuch a manner as not to impose a useless burden on the user, and canalso be provided with a sense of reassurance. As described above, thepath information may be provided before or after the agreementconcerning the use of the substitute parking service is concluded. Inthis specification, the term “service user” refers to both a person whois going to use substitute parking service, and a person who hasconcluded the agreement and receives the actual service.

In the management system according to the first aspect of thedisclosure, the path information may be transmitted when the pathindicated by the path information does not satisfy a path selectioncondition set by the service user. Namely, when the path satisfies thepath selection condition set in advance by the user, the pathinformation is not transmitted to the terminal, so that the procedure issimplified. However, even when the path selection condition issatisfied, the path information may be transmitted, so as to ask theservice user to check the path.

For example, the path selection condition may include a distance fromthe delivery location to the parking lot, which is acceptable to theservice user. The path selection condition may include an amount ofenergy consumption of the vehicle required for movement from thedelivery location to the parking lot, which amount is acceptable to theservice user. The amount of energy consumption is the amount ofconsumption of fuel, such as gasoline, light oil, or hydrogen, or theamount of consumption of electric power from a secondary battery. Theamount of energy consumption may be represented by the amount ofconsumption of fuel or electric power, or may be represented by anamount of money into which the consumption amount of the fuel or poweris converted. The path selection condition may be a combination of theabove conditions. The path selection condition is not limited to thoseas described above, but a condition(s) other than those as describedabove may be used.

In the management system, the processor may be configured to issue aspecific benefit to the service user, when an approval of the path thatdoes not satisfy the path selection condition is received from theterminal of the service user. According to the management of thisaspect, it may be possible to reduce a complaint of the service user whohas to use the path against his/her intention. The specific benefitincludes a coupon, point, or the like, which can be used for purchase ofcertain goods or use of service. However, the specific benefit may beother than coupons and points.

In the management system according to the first aspect of thedisclosure, the processor may be configured to select a parking lot thatsatisfies a parking lot selection condition set by the service user,from parking lots in which the vehicle is allowed to be parked. Theprocessor may be configured to use information indicating a position ofthe parking lot selected by processor, as the parking lot informationindicating the position of the parking lot, to generate the pathinformation. For example, the parking selection condition may include adistance from the delivery location, parking fee acceptable to theservice user, specifications of the parking lot desired by the serviceuser, and so forth. The specifications of the parking lot may includethe type (flat or multilevel) of the parking lot or facility, the sizeof a parking space of the parking lot, the presence or absence of dooropen/close space, the required height of the parking space, and soforth, and at least one may be selected from these specifications. Withthe parking lot selection condition thus employed, the parking lotpermitted or desired by the service user is selected, so that theservice user has an enhanced sense of satisfaction with the use of theservice.

In the management system according to the first aspect of thedisclosure, the processor may be configured to send candidate pathinformation indicating a plurality of candidate paths from the deliverylocation to the parking lot, and cost information indicating a costinvolved in each of the candidate paths, to the terminal of the serviceuser, and receive path information indicating a path selected by theservice user from the candidate paths. As described above, the pathinformation of the path selected based on the path selection conditionmay be transmitted. However, when two or more candidate paths arepresented to the service user, and the service user selects one of thecandidate paths, the path desired by the service user can be used forprovision of the substitute parking service. The two or more candidatepaths may be selected based on the parking lot selection condition andpath selection condition, or may be selected based on a predeterminedcondition different from these selection conditions. The candidate pathsmay be two or more paths between the delivery location and one parkinglot, or may be two or more paths between the delivery location andrespective ones of two or more parking lots. Two or more paths may beindicated as candidates with respect to each of the two or more parkinglots.

For example, the information indicating the cost involved in each of thecandidate paths includes a distance from the delivery location to theparking lot, parking fee, and an amount of energy consumption requiredfor travel of the vehicle from the delivery location to the parking lot,with regard to each of the candidate paths. At least one of thedistance, parking fee, and the amount of energy consumption may be used.However, the cost may include an information element or elements(parameter(s)) other than those illustrated above.

A second aspect of the disclosure is concerned with a method ofassisting use of substitute parking service in which a substitute driverparks a vehicle of a service user, in place of the service user. Themethod includes the steps of: generating path information indicating apath along which the vehicle to be traveled from a delivery location atwhich the vehicle is delivered to the substitute driver to a parking lotin which the vehicle is allowed to be parked, based on delivery locationinformation indicating the delivery location, and parking lotinformation indicating a position of the parking lot, and transmittingthe path information to a terminal of the service user.

A third aspect of the disclosure is concerned with a non-transitorycomputer-readable storage medium storing a management program for use ina computer of a system that manages substitute parking service in whicha substitute driver parks a vehicle of a service user, in place of theservice user. The program causes the computer to execute the steps of:generating path information indicating a path along which the vehicle tobe traveled from a delivery location at which the vehicle is deliveredto the substitute driver to a parking lot in which the vehicle isallowed to be parked, based on delivery location information indicatingthe delivery location, and parking lot information indicating a positionof the parking lot, and transmitting the path information to a terminalof the service user.

A fourth aspect of the disclosure is concerned with a non-transitorycomputer-readable storage medium storing a management program for use ina computer of a terminal of a service user who uses substitute parkingservice in which a substitute driver parks a vehicle of the serviceuser, in place of the service user. The program causes the computer toexecute the steps of: obtaining path information indicating a path alongwhich the vehicle to be traveled from a delivery location at which thevehicle is delivered to the substitute driver to a parking lot in whichthe vehicle is allowed to be parked, from a management system thatmanages the substitute parking service, and presenting the pathinformation to the service user.

A fifth aspect of the disclosure is concerned with a method of assistinguse of substitute parking service in which a substitute driver parks avehicle of a service user, in place of the service user. The methodincludes the steps of: causing a terminal of the service user to obtainpath information indicating a path along which the vehicle to betraveled from a delivery location at which the vehicle is delivered tothe substitute driver to a parking lot in which the vehicle is allowedto be parked, from a management system that manages the substituteparking service, and presenting the path information to the serviceuser.

According to the disclosure, the service user can be provided with asense of reassurance about the substitute parking service.

DETAILED DESCRIPTION OF EMBODIMENTS

Referring to the drawings, a management system of substitute parkingservice according to one embodiment, a method of assisting the use ofthe service, and programs will be described. The configuration of theembodiment is illustrated as an example, and the disclosure is notlimited to the configuration of the embodiment.

System Configuration

FIG. 1 schematically shows a system of substitute parking serviceaccording to this embodiment. In FIG. 1, the system includes a userterminal 200A, substitute terminal 200B, and management system 400,which are connected to a network 1. For example, the network 1 is acommunication network, such as the Internet, and may employ a wide areanetwork (WAN) or other communication network. Also, the network 1 mayinclude a cellular network, such as LTE (Long Term Evolution), and awireless network, such as wireless LAN (Local Area Network) includingWi-Fi.

The user terminal 200A is a terminal device of a service user who usessubstitute parking service, and corresponds to the “terminal of theservice user”. The user terminal 200A may be a mobile terminal (acommunication terminal having portability), such as a smart device, likea feature phone, smartphone, or a tablet terminal, Personal DigitalAssistant (PDA), or a wearable computer, for example, or may be avehicle-mounted terminal installed on a vehicle 10 of the service user.

The substitute terminal 200B is a terminal device of a substitute driverwho parks the vehicle 10 of the service user, in place of the user, andcorresponds to the “terminal of the substitute driver”. The substituteterminal 200B may also be a mobile terminal similar to the user terminal200A, or a vehicle-mounted terminal. In sum, the user terminal 200A andthe substitute terminal 200B are only required to be movable, and ableto communicate with the management system 400 via the network 1, and maybe a device other than the mobile terminal and vehicle-mounted terminalas described above provided that the requirements are met. In thisembodiment, the case where the user terminal 200A and the substituteterminal 200B are mobile terminals will be described as one example. Amobile terminal that may be either the user terminal 200A or thesubstitute terminal 200B will be denoted as “mobile terminal 200”.

The vehicle 10 has a smart key system including a locking/unlockingdevice 300 and a key unit 100. The locking/unlocking device 300 gives aunique ID to a mobile device (called “electronic key”) that performswireless communications with the vehicle 10, and permits unlocking of adoor and starting of the engine when the ID obtained throughcommunications with the mobile device coincides with an ID registered inadvance in the vehicle 10. The key unit 100 is a device that permitslocking and unlocking of the vehicle 10 using the mobile terminal 200 inplace of the electronic key, without altering the vehicle 10. The keyunit 100 is placed at a given position (e.g., in a glove box) within thevehicle 10, and is supplied with electric power from a battery orsecondary battery of the vehicle 10. When the key unit 100 obtainsenablement data (data that temporarily permit operation of the vehicle10, such as unlocking of the vehicle 10 and starting of the engine) forenabling operation of the vehicle from the mobile terminal 200, the keyunit 100 behaves like the electronic key, and permits unlocking of thedoor and starting of the engine, for example. The “enablement data” maybe data (i.e., a program) that can be implemented by a computer, or datathat cannot be implemented. The “enablement data” may be data forproving that the person who carries the mobile terminal 200 is theperson permitted to operate the vehicle, or data for activating a deviceor program used for operation of the vehicle, or a program itself usedfor operation of the vehicle, or other data. In this embodiment, theenablement data is authentication information that is used by the keyunit 100 for authentication of the substitute terminal 200B, and alsobrings the vehicle 10 into a state where it can be operated by thesubstitute driver when the substitute terminal 200B is successfullyauthenticated.

The management system 400 corresponds to the “management system ofsubstitute parking service”. The management system 400 is managed by anoperator (service provider) of the substitute parking service, forexample. The management system 400 performs management of information(user information) about service users, information (substituteinformation) about substitute drivers, and parking lot information, userregistration processing, processing for accepting requests for use ofservice, calculation of a path from a delivery location of the vehicle10 to a parking lot, and presentation of the path to the service userconcerned. The management system 400 also operates as an issuance devicethat issues authentication information that permits operation of thevehicle 10 using the substitute terminal 200B.

Flow of Substitute Parking Service

Referring to FIG. 1, the flow of the substitute parking service will bedescribed. A person who wishes to use substitute parking serviceaccesses the management device 400 using the user terminal 200A, andperforms a user registration process so as to become a member (serviceuser) of the substitute parking service (<1> in FIG. 1). Then, theservice user operates the user terminal 200A when he/she asks forprovision of the substitute parking service, and accesses the managementdevice 400 so as to apply for use of the service (<2> in FIG. 1). In theapplication, information (such as the date and time of use, deliverylocation, parking lot, service fee, shared payment of parking fee, etc.)associated with an agreement on implementation of substitute parkingservice is transmitted between the management device 400 and the userterminal 200A. During the mutual transmission, information indicating apath or paths from the delivery location to the parking lot is provided(transmitted) as needed from the management device 400 to the userterminal 200A (<3> in FIG. 1).

Once the agreement on implementation of substitute parking service isconcluded, as a result of the mutual transmission, a substitute driverwho will park the vehicle is selected. In this embodiment, thesubstitute driver may be automatically selected by the management system400, or may be manually selected. The management system 400 sends asubstitute driving command including the delivery location andinformation of the vehicle 10, to the substitute terminal 200B of theselected substitute driver (<4> in FIG. 1). The selected substitutedriver goes to the delivery location of the vehicle 10 according to thesubstitute driving command, and the vehicle 10 is handed over to thesubstitute driver.

Upon delivery of the vehicle 10, operation to enable the substitutedriver to operate the vehicle 10 is performed. Namely, the substituteterminal 200B receives authentication information that permits operationof the vehicle 10, from the management device 400 (<5> in FIG. 1), andsupplies the authentication information to the key unit 100 of thevehicle 10. With the authentication information thus supplied, the keyunit 100 behaves like an electronic key in a smart key system, and thesubstitute driver becomes able to unlock the vehicle 10, start theengine, and drive the vehicle 10. Thus, in the substitute parkingservice according to this embodiment, the service user is not requiredto hand over the electronic key to the substitute driver, and therefore,need not be present at the delivery location. The substitute driverdrives the vehicle 10, to move the vehicle 10 to a parking lot where thevehicle 10 is to be parked, and park the vehicle 10 there. When parkingis completed, the substitute driver ceases to be enabled to operate thevehicle 10, through invalidation of the authentication information, forexample. Afterward, the service user goes to the parking lot where thevehicle 10 is parked, and picks up the vehicle 10.

Configuration of Mobile Terminal

In the following, each of the devices that realize the substituteparking service will be described in detail. FIG. 2 shows an example ofthe configuration of the mobile terminal 200 that can be used as theuser terminal 200A or the substitute terminal 200B. The mobile terminal200 includes a processor 21, storage device 22, wireless communicationcircuit 23, input device 24, display 25, GPS (Global Positioning System)receiver 26, and near field communication circuit 27.

The storage device 22 includes a main storage device and an auxiliarystorage device. The main storage device is used as a storage area forprograms and data, development area for programs, work area forprograms, and buffer area for communication data, for example. The mainstorage device is provided by a random access memory (RAM), or acombination of RAM and a read-only memory (ROM). The auxiliary storagedevice is used as a storage area for data and programs. The auxiliarystorage device is selected from, for example, a hard disc, solid statedrive (SSD), flash memory, and a non-transitory computer-readablestorage medium, such as an EEPROM (Electrically Erasable ProgrammableRead-Only Memory).

The wireless communication circuit 23 governs wireless communicationsaccording to a wireless communication system (such as LTE, or wirelessLAN (Wi-Fi)) supported by the mobile terminal 200. The input device 24includes keys, buttons, pointing device, touch panel, etc., and is usedfor entry of information. The display 25 is a liquid crystal display,for example, and displays information and data. The GPS receiverreceives a signal from a GPS satellite, and calculates the position ofthe mobile terminal 200. The near field communication circuit 27 governsnear field communications according to certain near field communicationstandards (such as NFC (Near Field Communication), BLE (Bluetooth(registered trademark) Low Energy), UWB (Ultra Wide Band), and Zigbee).

The processor 21 is a central processing unit (CPU), for example, andexecutes various programs stored in the storage device 22, thereby tocause the mobile terminal 200 to operate as the user terminal 200A orthe substitute terminal 200B.

Configuration of Management System

FIG. 3 shows an example of the configuration of the management system400. The management system 400 is a general-purpose informationprocessing device, such as a personal computer, or a work station, or adedicated information processing device, such as a server machine. Themanagement system 400 includes a processor 411, storage device 412,communication interface (communication IF) 413, input device 414, anddisplay 415.

Those similar to the processor 21, storage device 22, input device 24,and display 25 as described above may be used as the processor 411,storage unit 412, input device 414, and display 415. However, thosehaving different performance or capabilities from those used in themobile terminal 200 may be used, depending on differences in the use andthe purpose of use.

The communication IF 413 governs communication processing. As thecommunication IF 413, a network interface card (NIC) may be used, forexample. The communication IF 413 sends and receives data andinformation to and from the user terminal 200A and the substituteterminal 200B, via the network 1. The processor 411 executes variousprograms stored in the storage device 412, so that the management system400 operates as a device for managing the substitute parking service anda device for issuing authentication information.

At least a part of the processing performed by the processor 21 and theprocessor 411 may be carried out by a processor, such as DSP (DigitalSignal Processor) or GPU (Graphics Processing Unit), other than the CPU,or by a dedicated or general integrated circuit, such as ASIC(Application Specific Integrated Circuit) or FPGA (Field ProgrammableGate Array), or a combination of the processor and the integratedcircuit. The combination may be called microcontroller (MCU), SoC(System-on-a-Chip), system LSI (Large-Scale Integration), or chip set,for example.

Description of Database (DB)

In the storage device 412, a user database (user DB) 416, substitutedatabase (substitute DB) 417, and parking lot database (parking lot DB)418 are stored, as one example.

The user DB 416 stores user information. FIG. 4 shows an example of thedata structure of the user DB 416. In the user DB 416, personalinformation of each service user, vehicle information, key unitinformation, and service-use-related information are stored, inassociation with a user ID as identification information of the serviceuser. The user ID may be unique information among users. The personalinformation includes the name of the service user, contact information(the address, phone number, mail address, etc.), user terminalinformation, and so forth. The user terminal information is informationused when the management system 400 communicates with the user terminal200A, and includes the IP (internet Protocol) address or MAC (MediaAccess Control) address of the user terminal 200A, for example. Thepersonal information may further include information other than the onesillustrated above. The personal information is stored when the user isregistered, for example, but may be stored at other times.

The vehicle information includes information for visually specifying thevehicle 10. For example, the vehicle information includes the vehicletype, vehicle number (automobile registration number plate), color(e.g., coating color, or body color) of the vehicle, and so forth. Thevehicle information may further include characteristics that help thesubstitute driver find the vehicle 10, in addition to those as indicatedabove. For example, the information indicating such characteristics mayinclude information that contributes to identification of the vehicle10, and includes the presence of optional parts (e.g., a roof carrier,roof box, spare tire, etc.), the presence of special painting (use oftwo or more tones, drawing of an image), attachment of a sticker, and soforth. The vehicle information is stored in the user DB 416 when theuser applies for the use of the service, for example. However, thevehicle information may be stored at the time of user registration. Theregistration of the vehicle information is optional.

The key unit information is information concerning the key unit 100placed in the vehicle 10, and is used for issuing authenticationinformation that matches the key unit 100. In this embodiment, thepersonal information and vehicle information as indicated above areregistered by the service user. However, a part or all of these items ofinformation may be registered by a seller of the vehicle before itsdelivery, or in a plant where the vehicle 10 is assembled, in place ofthe service user.

The service-use-related information is information concerning the use ofthe service, and includes the date and time of use, delivery location ofthe vehicle 10, and so forth. The date and time of use indicates thescheduled time of delivery of the vehicle 10, for example. The date andtime of use may include the scheduled time of pickup of the vehicle 10.As the service-use-related information, information indicating a parkinglot selection condition or conditions desired by the service user, andinformation indicating a path selection condition or conditions arestored. In this embodiment, the parking lot selection conditionsindicate the specifications of the parking lot, which are permitted ordesired by the service user. The specifications indicate the type (flator multilevel) of the parking lot or facility, the size of each parkingspace of the parking lot, the presence or absence of door open/closespace, the required height of the parking space, and so forth. Any oneof the items indicating the above specifications may be used alone, or acombination of two or more items may be used. Each item may also beweighted. Conditions, such as a condition on the height of the parkingspace, which must be satisfied and otherwise the vehicle 10 is inhibitedfrom being parked, may be set as special conditions. The parking lotselection conditions are not limited to the above specifications.Selection of a parking lot based on the parking lot selection conditionsis optional, and may be omitted.

The path selection condition is a condition used for selecting one pathfrom two or more candidate paths. The “two or more candidate paths” maybe two or more paths between the delivery location and one parking lot,or may be a single path or two or more paths between the deliverylocation and each of two or more parking lots. The two or more candidatepaths have respective costs, and the path selection condition indicate acondition for selecting one path based on the cost.

As the information indicating the cost, at least one of the distancefrom the delivery location to the parking lot, parking fee, valueindicating the amount of consumption of energy required to move thevehicle from the delivery location to the parking lot of each candidate,is stored with regard to each of the two or more paths. The distance maybe the distance or length of a straight line leading to the parking lot,or may be the traveling distance of the vehicle 10. As the parking fee,a unit fee per hour may be indicated, or an approximate value of thetotal fee calculated from the scheduled time period of use of theparking lot may be indicated. The amount of energy consumption is theamount of consumption of fuel, such as gasoline, light oil, or hydrogen,or the amount of power consumption of a secondary battery, and dependson the drive source of the vehicle 10. The value indicating the amountof energy consumption may be a value indicating the amount ofconsumption of fuel or electric power (an approximate value can beobtained from the type of the vehicle 10), or may be a value obtained byconverting the amount of consumption into the amount of money. As theselection condition(s), any one of the above-indicated distance, parkingfee, and amount of energy consumption may be used alone, or acombination of two or more of these conditions may be used. Also,weighting (setting of priorities) may be performed on the distance,parking fee, and specifications. Further, in the user DB 416, thesubstitute driver ID and parking lot ID associated with the user ID ofthe service user can be registered, as information indicating therelevance (correspondence relationship) between the service user, andthe substitute driver and parking lot. The substitute driver ID and theparking lot ID are registered in the user DB 416 when the substitutedriver ID and the parking lot ID are searched for, using the user ID.The service-use-related information may include information other thanthose as described above. For example, information received from theuser terminal 200A and indicating the position of the vehicle 10 may bestored as the service-use-related information.

FIG. 5 shows an example of the data structure of the substitute DB 417.In the substitute DB 417, personal information of each substitute driverand status information are stored in association with a substitute ID asidentification information of the substitute driver, for example. Thesubstitute ID may be unique information among substitute drivers. Thepersonal information of the substitute driver includes the name of thesubstitute driver, contact information (e.g., the address, phone number,mail address, etc.) on the substitute driver, and substitute terminalinformation. The contact information of the substitute driver is usedfor individual contact with the substitute driver. The substituteterminal information includes identification information of thesubstitute terminal 200B, for example, the IP address or MAC address ofthe substitute terminal 200B, and is used for communications between themanagement system 400 and the substitute terminal 200B.

The status information includes at least one of the availability of thesubstitute driver, the area of his/her presence, position information,and moving speed. However, the status information may include furtheritems of information. The availability is information indicating whethereach substitute driver can undertake substitute parking. Theavailability is set to “not available (NG)” when the substitute driveris off-duty or has already been dispatched, and is set to “available(OK)” otherwise. The area of presence indicates a geographic area inwhich the substitute driver (substitute terminal 200B) is currentlylocated. The geometric area may be an administrative area or district,or may be an area defined by the operator according to a suitable rule,or may be within a circle of a given radius, which has a center at theposition of the substitute terminal 200B. The position informationindicates position information of the substitute terminal 200B. Themoving speed indicates the average moving speed of the substitute driverobtained from the position information. The number of samples used forcalculation of the average moving speed can be selected as appropriate.The area of presence, position information, and moving speed are usedfor choosing a fewer candidates from candidate substitute drivers.However, selection of the substitute driver using the status informationis optional. Further, in the substitute DB 417, the user ID and parkinglot ID associated with the substitute driver ID of the substitute drivercan be registered, as information indicating the relevance(correspondence relationship) between the substitute driver, and theservice user and the parking lot. The user ID and the parking lot ID areregistered in the substitute DB 417 when the user ID and the parking lotID are searched for, using the substitute driver ID.

FIG. 6 shows an example of the data structure of the parking lot DB 418.The parking lot DB 418 stores, in association with the parking lot ID asa unique ID provided for each parking lot, the name of the parking lot,location (position information) of the parking lot, contact informationof the administrator of the parking lot, information (specificationsinformation) indicating the above-indicated specifications of theparking lot, and information indicating the parking fee. However, all ofthese items of information are not entirely essential, and informationother than these items may be stored. Further, in the parking lot DB418, the user ID and the substitute driver ID associated with theparking lot ID of the parking lot can be registered, as informationindicating relevance (correspondence relationship) between the parkinglot, and the substitute driver and the service user. The user ID and thesubstitute driver ID are registered in the parking lot DB 418 when theuser ID and the substitute driver ID are searched for, using the parkinglot ID.

Example of Operation Upon User Registration

Next, an example of operation of the user terminal 200A and themanagement system 400 at the time of user registration of a service user(at the time of new registration, <1> in FIG. 1) will be described. Theflowchart of FIG. 7 shows a process performed by the processor 21 (FIG.2) of the user terminal 200A when the service user is registered usingthe user terminal 200A. FIG. 8 shows an example of a user registrationscreen. The flowchart of FIG. 9 shows a process performed by themanagement system 400 at the time of user registration.

As shown in FIG. 7, when a person wishes to be registered as a user,he/she accesses the management system 400 (a website (which will also becalled “operation site”) of the substitute parking service), using theuser terminal 200A (step S11). In step S11, the user terminal 200Aestablishes communication session with the management system 400 via thenetwork 1, such that information and data can be transmitted between theuser terminal 200A and the management system 400, using thecommunication session. The management system 400 provides information ona new registration screen, in response to the access from the userterminal 200A (step S21 in FIG. 9). The user terminal 200A can display ascreen (web page) based on screen information transmitted from theoperation site, on the display 25, by executing a browser in a program.The screen of information from the operation site may also be displayed,using a dedicated application installed on the user terminal 200A.

As shown in FIG. 8, the user registration screen displayed on thedisplay 25 has entry fields for personal information, such as a name, asuser information, vehicle information, such as a vehicle number, vehicletype, and color, and key unit information, and the processor 21 acceptsentry of each information (step S12). However, the items of informationthat can be entered using the user registration screen are not limitedto those as indicated above, but may be selected as needed. Oncenecessary matters are entered into the entry fields, and a finish button25 a is pushed, the processor 21 sends the user information thusentered, to the management system 400 (step S13). When the processor 411of the management system 400 receives the user information (step S22),it issues a user ID (step S23), and stores the user information inassociation with the user ID, in the user DB 416 (step S24). As userterminal information, a source IP address of packets used fortransmission of the user information is registered in the user DB 416.The management system 400 sends the user ID to the user terminal 200A(step S25). The processor 21 of the user terminal 200A receives the userID, and stores it in the storage device 22 (step S14). In this manner,user registration is completed. The user ID stored in the user terminal200A is attached to information transmitted to the management system400, and used for storage of the information into the correspondingrecord of the user DB 416.

Example of Operation Upon Request for Service

Next, an example of operation of the management system 400 at the timewhen the service is requested (<2> in FIG. 1) will be described. Themanagement system 400 is operable in one of an automatic selection modeand a manual selection mode. In the automatic selection mode, themanagement system 400 automatically selects one path from two or morepaths, based on the parking lot selection conditions and the pathselection conditions, and presents the selected path to the serviceuser. In the manual selection mode, the management system 400 presentstwo or more candidate paths selected based on the parking lot selectionconditions and path selection conditions, to the service user, andallows the service user to select one of the paths. However, themanagement system 400 may be configured to operate only in either one ofthe automatic selection mode and the manual selection mode.

Example of Operation in Automatic Selection Mode

FIG. 10 shows the flow of processing of the management system 400 from arequest for use of substitute parking service to a substitute parkingprocess (output of a substitute driving command). In step S31, theprocessor 411 of the management device 400 obtains information on arequest from a service user. Namely, when the user terminal 200Aaccesses the management system 400 (the operation site), and logs in byuse of the user ID, the management system 400 sends information on a userequest screen or form of the substitute parking service, to the userterminal 200A. The processor 21 of the user terminal 200A displays theuse request screen on the display 25.

FIG. 11 shows an example of display of the use request screen. The userequest screen includes respective entry fields for the date and time ofuse (date and time of delivery), delivery location, parking lotselection conditions, and path selection conditions, radio buttons 25 bused for selecting one of the automatic selection mode and the manualselection mode, and a request button 25 c. As the date and time of use,the date and time of delivery of the vehicle 10 are entered. The dateand time of use may further include the scheduled pickup time of thevehicle 10. The delivery location may be information of a location wherethe vehicle 10 is stopped for delivery, or information indicating apoint (delivery position) of stopping of the vehicle narrower than thelocation. When the delivery location is entered (designated), arepresentative point of this location is used as the delivery position.

In the entry field of the parking lot selection conditions, the contentpermitted or desired by the service user, with regard to thespecifications of the parking lot, is entered. Also, in the entry fieldof the path selection conditions, conditions permitted or desired by theservice user, with regard to the distance between the delivery locationand the parking lot, parking fee, and the amount of energy consumption,are entered. As the entry fields of the parking lot selection conditionsand the path selection conditions, on the user request screen, aplurality of choices or options provided in advance for thespecifications, distance, parking fee, and the amount of energyconsumption may be presented in the form of check boxes or pull-downmenus, so as to allow the service user to make selections. Regardingentry of the parking lot selection conditions and path selectionconditions, a menu listing “type prioritized”, “size of parking spaceprioritized”, “distance prioritized”, “parking fee prioritized”, and“energy consumption amount prioritized” may be displayed, instead ofrequesting the user to enter or select detailed conditions, and theorder of priority of condition items may be set, so that the path isselected based on the top priority condition item. The radio buttons 25a are used for selecting one of the automatic selection mode and themanual selection mode. The request button 25 c is a button indicatingcompletion of entry of the request information and generating a commandto send the request information.

The user enters request information, including the date and time of use(e.g., the time of delivery), delivery location, parking lot selectionconditions, and path selection conditions, using the use request screen,and pushes the request button 25 c. Then, the user terminal 200A sendsthe request information entered using the use request screen, to themanagement system 400. In this manner, the processor 411 of themanagement system 400 obtains the request information. The parking lotselection conditions and the path selection conditions may be entered,using the user registration screen, at the time of registration of theuser.

In step S32, the processor 411 of the management system 400 selects aparking lot that satisfies the parking lot selection conditions, from alist of parking lots stored in the parking lot DB 418, using theinformation indicating the delivery location in the request information,and information (if entered) indicating the parking lot selectionconditions. A single parking lot, or two or more parking lots, may beselected in step S32. When there is no parking lot that satisfies theparking lot selection conditions, the processor 411 selects a givennumber of parking lots according to a predetermined rule.

In step S33, the processor 411 of the management system 400 calculates apath from the delivery location, to each of the parking lots selected instep S32. In step S34, the processor 411 of the management system 400determines whether there is any path that satisfies the path selectionconditions set by the service user and included in the requestinformation. The processor 411 proceeds to step S38 when it determinesthat there is such path, and proceeds to step S35 when there is no suchpath. When the parking lot selection conditions are not satisfied eventhough there is a path that satisfies the conditions in step S34, theprocessor 411 proceeds to step S35.

In step S35, the processor 411 of the management device 400 sends pathinformation including information indicating the path from the deliverylocation to the parking lot, information to the effect that one or bothof the parking lot selection conditions and the path selectionconditions is/are not satisfied, and information of the parking lot as adestination of the path obtained from the parking lot DB 418, from thecommunication IF 413 to the user terminal 200A. The path information mayfurther include information indicating the distance of the path, parkingfee, and the amount of energy consumption. At this time, pathinformation indicating information on two or more paths may betransmitted.

Upon receipt of the path information, the processor 21 of the userterminal 200A displays a screen based on the path information, on thedisplay 25. On the screen based on the path information, the path fromthe delivery location to the parking lot, information on the parkinglot, and information to the effect that one or both of the parking lotselection conditions and the path selection conditions is/are notsatisfied, are displayed. The path may be displayed in the form ofletters, or an image or video showing the path on a map, or acombination thereof. When a single path is presented, the service userenters approval or non-approval of the path, using the input device 24.When two or more paths are presented, the service user entersnon-approval of all of the paths, or approval of a selected one of thepaths, using the input device 24. The response including the informationindicating approval or non-approval of the path is transmitted from theuser terminal 200A to the management system 400. In connection withoperation of the user terminal 200A, the processor 21 and the wirelesscommunication circuit 23 operate as a means for obtaining the pathinformation from the management system 400, and the processor 21 and thedisplay 25 operate as a means for presenting the path information to theservice user. Also, the processor 21 operates as a display control meansfor controlling display of the path information on the display 25(display device). However, the path information may be provided by voiceto the service user.

In step S36, the processor 411 of the management device 400 determineswhether the service user permits the path that does not satisfy theconditions. When information indicating approval of the path is includedin the response received from the user terminal 200A, the processor 411determines that the service user permits the path, and proceeds to stepS37. On the other hand, when information indicating non-approval of thepath is included in the response, the processor 411 determines that theagreement on service use is not concluded, and finishes the process.

In step S37, the processor 411 issues a specific benefit to the serviceuser. For example, the processor 411 generates information indicating acertain coupon or point, as a specific benefit, and sends information ofthe user ID and the coupon or point to an information processing unit(not shown) that manages the coupon or point, so as to ask theinformation processing unit to create an environment where the coupon orpoint can be used. Alternatively, the processor 411 may generate a codefor obtaining screen information of a coupon or a point, and sends thecode to the user terminal 200A, thereby to issue the coupon or point. Itis, however, to be noted that the issuance of the specific benefit isoptional.

In step S38, the processor 411 sends information to the effect that theagreement on the substitute parking service has been concluded, to theuser terminal 200A. In step S39, the processor 411 performs a substituteparking process. In the substitute parking process, a process ofautomatically selecting a substitute driver, and others, are performed.

More specifically, the processor 411 of the management device 400 canautomatically select the substitute driver in the following manner. Forexample, the processor 411 can pick out substitute drivers who areavailable (OK) for substitute parking, referring to the substitute DB417, and randomly select one from the substitute drivers having thedelivery location within the area of his/her presence. In anotherexample, the processor 411 may select a substitute driver whose positionindicated by the position information is spaced by a short distance fromthe delivery location. In a further example, the processor 411 mayselect a substitute driver having a high moving speed, from among thesubstitute drivers each having the delivery location within an area ofhis/her presence. The method of selecting the substitute driver can beselected as appropriate, according a predetermined selection rule usinga single parameter or a combination of parameters included in the statusinformation. The processor 411 links the substitute ID of the selectedsubstitute driver with the user ID of the service user. The processor411 also links the user ID of the service user, with the parking lot IDof the parking lot used for parking of the vehicle 10 of the serviceuser. In this embodiment, the processor 411 registers the correspondencerelationship among the user ID, substitute ID, and parking lot ID, inthe substitute DB 417. However, the correspondence relationship may beregistered in the user DB 416 or the parking lot DB 418. The processor411 sends a command for substitute driving of the vehicle 10, to thesubstitute terminal 200B, using the substitute terminal informationcorresponding to the substitute ID (<4> in FIG. 1).

At this time, the processor 411 obtains corresponding user informationfrom the user DB 416, using the user ID retrieved from the substitute DB417 using the substitute ID, and obtains corresponding parking lotinformation from the parking lot DB 418, using the parking lot IDretrieved from the substitute DB 417 using the substitute ID. Thesubstitute driving command includes user information (the user name,contact information, vehicle information, key unit information, the dateand time of use, delivery location) corresponding to the user ID linkedwith the substitute driver ID, and parking information corresponding tothe parking lot ID. The substitute driver can go to the deliverylocation, and receive authentication information issued, using the userinformation in the substitute driving command received by the substituteterminal 200B. Also, the substitute driver can drive the vehicle 10 tothe parking lot, in place of the user, using the parking lot informationreceived by the substitute terminal 200B. For example, the substitutedriver can set the parking lot indicated by the parking lot information,as a destination of a car navigation system included in the substituteterminal 200B or the vehicle 10, and drive the vehicle 10 according to acommand from the car navigation system, so as to move the vehicle 10 tothe parking lot.

While the parking lot selection conditions and the path selectionconditions are used in the example of the process shown in FIG. 10, theparking lot selection conditions may not be used (set to OFF) or may beomitted. In this case, step S33 and subsequent steps are executed, withrespect to a given number of parking lots picked out from a listaccording to a predetermined rule. For example, parking lots locatedwithin a circle of a given radius from the delivery location are pickedout.

In the example of the process shown in FIG. 10, when there is a paththat satisfies the parking lot selection conditions and the pathselection conditions in step S34, the path information is nottransmitted to the user terminal 200A. However, when an affirmativedecision (YES) is obtained in step S34, the path information indicatingthe path that satisfies the parking lot selection conditions and thepath selection conditions may be transmitted from the management system400 to the user terminal 200A, and the management system 400 may receiveinformation indicating confirmation from the user terminal 200A.

Example of Operation in Manual Selection Mode

FIG. 12 shows the flow of processing of the management system 400 from arequest for use of substitute parking service to a substitute parkingprocess (output of a substitute driving command), in the manualselection mode. Steps S41 to S43 in FIG. 12 are substantially identicalwith steps S31 to S33 shown in FIG. 10, and therefore, will not bedescribed. However, in step S43, a given number of paths are picked out,irrespective of whether the parking lot selection conditions aresatisfied. For example, with regard to two or more paths between thedelivery location and one parking lot, a path having the shortestdistance as a path corresponding to “distance prioritized”, and a pathhaving the cheapest parking fee as a path corresponding to “parking feeprioritized”, are picked out as two or more candidate paths. In anotherexample, two or more paths selected according to the parking lotselection conditions, path selection conditions, etc. from a pluralityof paths between the delivery location and each of two or more parkinglots may be picked out as two or more candidate paths.

In step S44, the processor 411 of the management system 400 sends pathinformation indicating the two or more paths picked out in step S43,from the communication IF 413 to the user terminal 200A. The pathinformation includes information indicating at least one of the distanceof each candidate path indicated in the path information, parking fee,and the amount of energy consumption. The path information may alsoinclude information to the effect that the path does not satisfy atleast one of the parking lot selection conditions and path selectionconditions when at least one of the conditions is not satisfied.

Upon receipt of the path information, the processor 21 of the userterminal 200A displays a screen based on the path information, on thedisplay 25. On the screen based on the path information, each candidatepath from the delivery location to the parking lot, information on theparking lot, and information to the effect that one or both of theparking lot selection conditions and the path selection conditionsis/are not satisfied, are displayed. The path may be displayed in theform of letters, or an image or video showing the path on a map, or acombination thereof. The service user selects non-approval of all of thepaths, or selects one of the two or more paths, and enters approval ofthe selected path, using the input device 24. The response includinginformation indicating approval or non-approval of the path istransmitted from the user terminal 200A to the management system 400,and received by the management system 400 (step S45).

In step S46, the processor 411 of the management system 400 determineswhether the response includes information indicating non-approval of theroutes. When the processor 411 determines that the response includesinformation indicating non-approval, the agreement on the substituteparking service is not concluded, and the process ends. When theresponse does not include the information of non-approval, the processor411 proceeds to step S47.

In step S47, the processor 411 determines whether the path selected andapproved by the service user satisfies both the parking lot selectionconditions and path selection conditions set by the service user. Whenthe processor 411 determines that both of the conditions are satisfied,it proceeds to step S49. If not, the processor 411 proceeds to step S48.Step S48 is identical with step S37 of FIG. 10, and steps S49 and S50are identical with steps S38 and S39; therefore, these steps will not bedescribed. Step S48 is optional. When transmission of the substitutedriving command is completed, the management system 400 sends anotification that the vehicle 10 is to be stopped at the deliverylocation at the date and time of use, to the service user, for example,and finishes the process.

Processing on Substitute Terminal

When the substitute terminal 200B receives the user information, thesubstitute driver is informed that he/she has been selected as thesubstitute driver of the vehicle 10, and moves to the delivery locationof the vehicle 10. The substitute driver may move on foot, or may use avehicle (including a two-wheel vehicle, and a bicycle) for moving, orother moving means. The vehicle of the substitute driver may be drivenby himself/herself, or may be driven by a fellow passenger. For example,it is preferable that the substitute driver goes to the deliverylocation, along with a companion, by a vehicle for moving, and has thecompanion drive the vehicle and pick up the substitute driver, after thesubstitute driver parks the vehicle 10 in place of the service user. Thesubstitute driver may cause the substitute terminal 200B to receive theposition of the vehicle 10 which the management system 400 receives fromthe user terminal 200A, and head for the delivery location, using theposition of the vehicle 10 as a hint.

When the substitute driver finds the vehicle 10 at the deliverylocation, the substitute driver operates the substitute terminal 200B tosend a request for issuance of authentication information to themanagement system 400 (<5> in FIG. 1). The substitute terminal 200B canobtain the address of the management system 400, through learning of asource address of the substitute driving command. Alternatively, themanagement system 400 may designate a delivery address of a request forissuance of authentication information.

When the management system 400 receives the request for issuance, itrefers to key unit information of the service user, in the user DB 416,obtains authentication information (stored in advance in the storagedevice 412, for example) corresponding to the key unit information, andsends the authentication information to the substitute terminal 200B(<5> in FIG. 1). The wireless communication circuit 23 of the substituteterminal 200B receives authentication information as enablement datafrom the management system 400, via the network 1. The processor 21 ofthe substitute terminal 200B sends the authentication informationreceived from the management system 400, to the key unit 100(vehicle-mounted unit), so that the key unit 100 behaves like anelectronic key. As a result, the door of the vehicle 10 is unlocked, andthe engine is started when an engine start button provided in thevehicle 10 is pushed. Namely, the vehicle 10 is brought into an operablestate in which the vehicle 10 can be driven.

The substitute driver opens the door of the vehicle 10, and starts theengine, to head for a destination (the parking lot of the vehicle 10) bydriving the vehicle 10. After stopping the vehicle 10 in the parkinglot, the substitute driver comes out of the vehicle 10, and performs apredetermined disablement process. Through the disablement process, thekey unit 100 stops behaving like the electronic key, and the vehicle 10ceases to be in the operable state, and is locked. As a result, thesubstitute driver becomes unable to unlock the vehicle 10 again anddrive the vehicle 10.

In the above description, the substitute terminal 200B sends the requestfor issuance of authentication information after the substitute driverarrives at the delivery location. However, the substitute terminal 200Bmay send the request for issuance at an appropriate time after receivingthe substitute driving command, and receive the authenticationinformation. Also, in this embodiment, the management device 400 waitsfor receipt of the request for issuance, and then sends theauthentication information to the substitute terminal 200B; however, itmay be considered to omit the step of receiving the request forissuance, and send the authentication information along with thesubstitute driving command.

In operation of the management system 400 as described above, theprocessor 411 operates as a means for generating path information, meansfor issuing a specific benefit, and means for selecting a parking lot.Also, the communication IF 413 operates as a means for communicatingwith the user terminal 200A and the substitute terminal 200B, and theprocessor 411 and the communication IF 413 operate as a transmittingmeans for transmitting the path information to the user terminal 200A.

Locking/Unlocking System Including Key Unit

Here, one example of a locking/unlocking system including the key unit100 that performs locking/unlocking of the vehicle 10 will be described,using FIG. 13 and FIG. 14. As shown in FIG. 13, the locking/unlockingsystem includes the key unit 100 and locking/unlocking device 300installed on the vehicle 10, substitute terminal 200B, and managementsystem 400. In the locking/unlocking system, the key unit 100 has awireless interface similar to an electronic key (mobile device) of asmart key system, and communicates with the existing locking/unlockingdevice 300, so as to lock and unlock the vehicle 10 without using aphysical key. The key unit 100 also performs near field communicationwith the substitute terminal 200B, and determines whether the key unit100 behaves like the electronic key of the vehicle 10, based on theresult of authentication of the substitute terminal 200B. The substitutedriver can lock and unlock the vehicle 10, by operating the substituteterminal 200B from the outside of the vehicle 10.

System Configuration

In FIG. 14, the locking/unlocking device 300 locks and unlocks the doorof the vehicle 10, in response to a locking signal and an unlockingsignal transmitted via radio waves of a high-frequency (radio-frequency,which will be called “RF”) zone, from an electronic key (which will becalled “mobile device”) carried by the user (service user) of thevehicle 10. The locking/unlocking device 300 also has a function oftransmitting radio waves of a low-frequency (which will be called “LF”)zone, so as to search for the mobile device. The key unit 100 sends andreceives radio waves of the RF zone and LF zone to and from thelocking/unlocking device 300, in place of the mobile device carried bythe user, so as to control locking and unlocking of the door of thevehicle 10.

The locking/unlocking device 300 includes an LF transmitter 301, RFreceiver 302, matching electronic control unit (ECU) 303, bodyelectronic control unit (ECU) 304, and door lock actuator 305. The LFtransmitter 301 transmits radio waves of a low-frequency zone (e.g., 100KHz to 300 KHz) for searching for (polling) the key unit 100. The LFtransmitter 301 is incorporated in the vicinity of the center console orsteering wheel in the cabin, for example. The RF receiver 302 receivesradio waves of a high-frequency zone (e.g., 100 MHz to 1 GHz)transmitted from the key unit 100. The RF receiver 302 is placed at anylocation within the cabin.

The matching ECU 303 performs control to lock and unlock the door of thevehicle 10, based on a signal (locking signal or unlocking signal)transmitted from the key unit 100 via radio waves of the RF zone. Thematching ECU 303 is provided by a microcomputer, for example. In thefollowing description, the locking signal and the unlocking signal willbe collectively called “locking/unlocking signal”. The term“locking/unlocking signal” represents at least one of the locking signaland the unlocking signal.

The matching ECU 303 certifies that the locking/unlocking signaltransmitted from the key unit 100 was transmitted from a proper device.More specifically, the matching ECU 303 determines whether a key IDincluded in the locking/unlocking signal coincides with a key ID storedin advance in a storage unit of the matching ECU 303. Then, the matchingECU 303 sends an unlocking command or a locking command to the body ECU304, based on the result of this determination. The unlocking command orlocking command is transmitted via an in-vehicle network, such as CAN(Controller Area Network).

The body ECU 304 is a computer that controls the body of the vehicle 10.The body ECU 304 unlocks and locks the vehicle 10, by controlling thedoor lock motor 305 based on the unlocking command or locking commandreceived from the matching ECU 303. The door lock motor 305 is anactuator that locks and unlocks the door (including a trunk, as well asa door for boarding and a rear gate) of the vehicle 10. The door lockmotor 305 operates based on a signal from the body ECU 304.

The key unit 100 authenticates the substitute terminal 200B byconducting near field communication with the substitute terminal 200B,and sends the locking/unlocking signal, using radio waves of the RFzone, based on the result of the authentication. As one example, the keyunit 100 includes an LF transmitter 101, RF transmitter 102, near fieldcommunication unit 103, and controller 104. The LF receiver 101 receivesa polling signal transmitted via radio waves of the LF zone, from thelocking/unlocking device 300. The LF receiver 101 has an antenna (whichwill be called “LF antenna”) for receiving the radio waves of the LFzone. The RF transmitter 102 sends the locking/unlocking signal to thelocking/unlocking device 300, via radio waves of the RF zone.

The near field communication unit 103 communicates with the substituteterminal 200B. The near field communication unit 103 conductscommunications in a short range or distance (to an extent that permitscommunications between the inside of the cabin and the outside of thecabin), using a certain wireless communication standard. As one examplethe near field communication unit 103 performs data communications basedon the BLE. The BLE is a low energy communication standard using theBluetooth (registered trademark), and is characterized in that onedevice can immediately start communicating with the other device upondetection of the other device, without requiring pairing of the twodevices.

The controller 104 performs control to authenticate the substituteterminal 200B, by conducting near field communication with thesubstitute terminal 200B via the near field communication unit 103, andperforms control to send the locking/unlocking signal based on theresult of the authentication. The controller 104 includes a processorand a memory, for example, and the processor executes control programsstored in the memory for controlling the key unit 100, so as toimplement various functions. For example, the controller 104 has afunction of receiving a polling signal transmitted as radio waves of theLF zone from the locking/unlocking device 300, via the LF receiver 101,a function of sending the locking/unlocking signal in the form of radiowaves of the RF zone to the locking/unlocking device 300, via the RFtransmitter 102, a function of processing communications with thesubstitute terminal 200B conducted via the near field communication unit103, a function of producing the locking/unlocking signal when thesubstitute terminal 200B is successfully authenticated, and so forth.

The controller 104 performs operation to authenticate the substituteterminal 200B, based on authentication information included in a lockingrequest or unlocking request (which will be collectively called“locking/unlocking request”) transmitted from the substitute terminal200B. The controller 104 compares authentication information stored inthe memory, with the authentication information transmitted from thesubstitute terminal 200B, and determines that the substitute terminal200B is successfully authenticated when these pieces of information havea predetermined relationship. When the predetermined relationship is notrecognized, the controller 104 determines that the authenticationfailed. When the substitute terminal 200B is successfully authenticated,a locking/unlocking signal produced according to the request receivedfrom the substitute terminal 200B is transmitted to thelocking/unlocking device 300 via the RF transmitter 102. Theauthentication method may be a method by which the identity is checkedby simply comparing the two pieces of authentication information witheach other, or may be a method using asymmetric cipher. In the followingdescription, the authentication information stored in the key unit 100will be called “device authentication information”, and theauthentication information transmitted from the substitute terminal 200Bwill be simply called “authentication information”, where appropriate.

The key unit 100 transmits an ID of the electronic key (which will becalled “key ID”), along with the locking/unlocking signal, to thelocking/unlocking device 300. The key ID may be stored in advance in theform of plain text in the key unit 100, or may be stored in an encryptedform.

The substitute terminal 200B will be described. The substitute terminal200B functions as a device that performs processing or operation as anear field communication unit 201, communication unit 202, controller203, and input/output unit 204, when the processor 21 is loaded withprograms stored in the storage device 22 and executes the programs. Thenear field communication unit 201, which corresponds to the near fieldcommunication circuit 27, communicates with the key unit 100, accordingto the same communication standard as that of the near fieldcommunication unit 103. The communication unit 202, which corresponds tothe wireless communication circuit 23, connects the substitute terminal200B to the network 1, and governs communications with the managementsystem 400, etc. The communication unit 202 communicates with otherdevices (such as the management system 400) via the network 1, usingmobile communication service, such as 3G (3rd Generation), or LTE (LongTerm Evolution).

The controller 203, which corresponds to the processor 21, performsoperation to produce a locking/unlocking request, operation to obtainthe authentication information, and operation to send thelocking/unlocking request and the authentication information to the keyunit 100, for example. The controller 203 also performs operation torewrite control programs stored in the memory of the key unit 100, aswill be described later, in addition to the above operations. Thecontroller 203 interacts with the substitute driver via the input/outputunit 204. The input/output unit 204, which corresponds to the inputdevice 24 and the display 25, accepts input operation performed by thesubstitute driver, and presents information to the user.

The controller 203 displays an operation screen on the input/output unit204, and produces an unlocking request or a locking request, accordingto operation performed by the substitute driver. For example, thecontroller 203 outputs an icon for unlocking, icon for locking, or thelike, on a touch panel display, and produces an unlocking request or alocking request, based on operation performed by the substitute driver.The operation performed by the substitute driver is not limited to theone via the touch panel display, but may be performed via a hardwareswitch, or the like, for example.

The controller 203 performs operation to obtain authenticationinformation from the management system 400. The authenticationinformation is not the information with which the locking/unlockingdevice 300 authenticates the key unit 100, but information with whichthe key unit 100 authenticates the substitute terminal 200B. Morespecifically, the controller 203 sends a signal requesting issuance ofauthentication information, along with information that identifies thesubstitute terminal 200B, to the management system 400, via thecommunication unit 202. The management 400 that receives this signalobtains authentication information unique to the substitute terminal200B, and sends the obtained authentication information to thesubstitute terminal 200B. As a result, it becomes possible to performoperation to unlock the vehicle 10, on the substitute terminal 200B.When the substitute terminal 200B does not have the authenticationinformation, it is impossible to perform locking operation and unlockingoperation on the operation screen. The authentication informationobtained by the substitute terminal 200B may be a permanent key, or aone-time key. In either case, the device authentication informationcorresponding to the authentication information is stored in advance inthe key unit 100.

Invalidation of Authentication Information

The state in which the substitute driver is permitted to operate thevehicle 10 is cancelled in the following manner. For example, themanagement device 400 invalidates authentication information issued bythe substitute terminal 200B. The content of a specific process ofinvalidating the authentication information is not particularly limited,provided that the substitute driver can be inhibited from operating thevehicle 10 again after completing parking, by use of the substituteterminal 200B.

To invalidate the authentication information, the management system 400performs any of operations (1) to (7) below. However, methods ofinvalidation other than those as described below may be employed,provided that the substitute driver is inhibited from unlocking the dooror driving again, after completing substitute parking of the vehicle.(1) A command to delete the authentication information is given to thesubstitute terminal 200B. (2) A command to set an invalidation flag ofauthentication information to ON is given to the substitute terminal200B. In this case, while the invalidation flag is ON, the substituteterminal 200B is placed in a state where it does not send authenticationinformation. (3) A command to rewrite the period of validity of theauthentication information to expire on some date and time in the pastis given to the substitute terminal 200B. The substitute terminal 200Bdeletes the authentication information that has passed the period ofvalidity. (4) A fact that the authentication information is invalid anda command to inhibit transmission of the invalid authenticationinformation are given to the substitute terminal 200B. (5) Themanagement system 400 communicates with the key unit 100, and gives acommand to inhibit the key unit 100 from accepting invalidauthentication information, to the key unit 100. (6) The managementsystem 400 communicates with the key unit 100, and gives a command toinhibit the vehicle 10 from accepting authentication information fromthe substitute terminal 200B, to the key unit 100. (7) It may beconsidered to manually delete the authentication information from thesubstitute terminal 200B, without requiring the management system 400 tocommunicate with other devices.

First Modified Example of Locking/Unlocking System

In the above example of the locking/unlocking system, when theauthorization process is successfully performed in the key unit 100, thevehicle 10 is unlocked by the locking/unlocking device 300. Instead, theprocess performed in the key unit 100 may be carried out in thelocking/unlocking device 300. Namely, the locking/unlocking device 300may include a control unit (ECU) for authenticating the authenticationinformation received from the substitute terminal 200B, and the controlunit may send an unlocking command or locking command to the body ECU304, via an in-vehicle network, such as CAN, when the substituteterminal 200B is successfully authenticated. In this manner, thesubstitute driver can bring the vehicle 10 into an operable state, witha single arrangement that does not include the key unit 100.

Second Modified Example of Locking/Unlocking System

In the above example of the locking/unlocking system, the substituteterminal 200B receives authentication information as enablement data ofthe vehicle 10, from the management system 400. When the substituteterminal 200B is authenticated based on the authentication information,the locking/unlocking signal is transmitted from the key unit 100 to thelocking/unlocking device 300, and the vehicle 10 is locked or unlocked.The authentication information may not be information for authenticatingthe substitute terminal 200B, but may include information of the key IDfor locking or unlocking the vehicle 10. In this case, the substituteterminal 200B receives authentication information including the key IDfrom the management system 400, and sends the received key ID, alongwith the locking/unlocking signal, to the locking/unlocking device 300.The locking/unlocking device 300 checks the received key ID against thekey ID stored in advance in the locking/unlocking device 300, and locksor unlocks the vehicle 10 when the key IDs match each other. The key IDmay be sent and received in an encrypted form, between the substituteterminal 200B, and the management system 400 or the locking/unlockingdevice 300. The management system 400 may produce a one-time key, byencrypting or encoding the key ID along with time information accordingto a predetermined algorithm. The locking/unlocking device 300 maydecrypt the received one-time key, by a method corresponding to the samepredetermined algorithm as that used by the management system 400, andcheck it against the key ID stored in advance in the locking/unlockingdevice 300. The one-time key may also be transmitted from the managementsystem 400 to a lending management server (not shown), and transmittedfrom the lending management server to the substitute terminal 200B. Inany case, the substitute terminal 200B achieves invalidation, bydeleting the one-time key upon a lapse of a predetermined time fromreceipt of the one-time key. With the one-time key produced from the keyID and time information thus included in the authentication information,the management system 400 can produce temporarily valid authenticationinformation, for each event of substitute parking, and send it to thesubstitute terminal 200B.

Third Modified Example of Locking/Unlocking System

In the above example of the locking/unlocking system, the managementsystem 400 may send authentication information for the substituteterminal 200B corresponding to fixed authentication information uniqueto the key unit 100, to the substitute terminal 200B, and may send thekey ID stored in advance in the locking/unlocking device 300 of thevehicle 10, to the substitute terminal 200B. However, the managementsystem 400 may produce new authentication information and issue it tothe substitute terminal 200B, each time the management system 400receives a request for authentication information, from the substituteterminal 200B. In this case, the management system 400 may store deviceauthentication information for the key unit 100 corresponding to the newauthentication information for the substitute terminal 200B, in the keyunit 100, via a vehicle-mounted communication device (not shown) thatcan communication with the network 1 to which the substrate terminal200B is connected. In this case, the key unit 100 may be connected tothe vehicle-mounted communication device via the CAN, or the like.However, the management system 400 may produce new authenticationinformation, based on identification information used for identifyingthe vehicle 10, and time information, and pass the new authenticationinformation and the time information to the substitute terminal 200B. Inthis case, the key unit 100 may produce new authentication information,by a method corresponding to the same algorithm as that of themanagement system 400. The substitute terminal 200B may send the newauthentication information and the time information to the key unit 100,so as to be authenticated.

Unloading from Parking Lot

The service user goes to the parking lot where the vehicle 10 is parkedby the substitute driver, and picks up the vehicle 10 by unloading thevehicle 10 from the parking lot. Regarding unloading from the parkinglot, (a) the service user pays for the parking fee in some cases, and(b) the service provider pays for the parking fee in other cases. Whenthe service user pays for the parking fee, the service user may go tothe parking lot, pay for the parking fee, and unload the vehicle 10 fromthe parking lot. On the other hand, when the service provider pays forthe parking fee, operation as described below may be considered. Forexample, an automated parking fee machine provided in a parking lot iscaused to read a predetermined code. The predetermined code is, forexample, a code representing the service provider. The predeterminedcode may be held in an IC card provided from the service provider to theservice user, or the user terminal 200A may download the predeterminedcode from the management system 400, for example. The predetermined codeis linked with the parking fee, and the operator of the parking lotcollects the parking fee from the service provider.

As an optional service, service involving operation to unload thevehicle 10, and substitute driving to a location desired by the serviceuser, may be implemented. In this case, the authentication informationheld by the substitute terminal 200B may be used again, without beinginvalidated. In another example, the substitute terminal 200B may send arequest for issuance again, and obtain authentication information againfrom the management system 400.

Effects of Embodiment

According to the illustrated embodiment, path information indicating apath scheduled to be used for movement from the delivery location of thevehicle 10 to the parking lot is transmitted from the management system400 to the user terminal 200A. The user terminal 200A displays the pathinformation obtained from the management system 400 on the display 25,so as to present the path information to the service user. Thus, theservice user can refer to the information on the path scheduled to beused for movement of the vehicle 10. As a result, the service user, whenusing the substitute parking service, is less likely or unlikely to feelconcerned about the path used by the substitute driver for movement ofthe vehicle 10, and the amount of energy consumption (fuel consumption)required for movement, and reassurance can be given to the service user.With reassurance thus provided, the service user can more easily make adecision on the agreement. Also, in making the agreement, it may bepossible to give further reassurance to the service user, by promisingthat a record of the path actually used will be provided to the serviceuser. For example, the management system 400 may obtain positioninformation of the substitute terminal 200B, and record a movement pathof the vehicle 10 during movement to the parking lot, or record an imageor video using the substitute terminal 200B. After the use of theservice, the management system 400 may provide the record of the path tothe service user, and prove that the vehicle 10 moved along the pathagreed by the service user. It may also be possible to provide pathinformation to the service user after concluding the agreement. In thiscase, too, reassurance can be given to the service user.

According to the embodiment, when the path satisfies the parking lotselection conditions and path selection conditions which the serviceuser provided in advance to the management system 400, the agreement isconcluded without requiring transmission of the path information. Thus,the path having the content permitted or desired by the service user isselected, while the procedure can be simplified by omitting provision ofthe path information.

According to the embodiment, when the service user gives approval to apath that does not satisfy (meet) the parking lot selection conditionsand path selection conditions, a specific benefit is granted to theservice user, so that complaint of the service user can be reduced.

According to the embodiment, the vehicle 10 is parked in the parking lothaving the specifications desired by the service user, under the parkinglot selection conditions, so that the service user can more easily pickup (unload) the vehicle 10, resulting in enhancement in the sense ofsatisfaction of the service user. Also, the service user is providedwith information, such as the distance to the parking lot, parking fee,and the amount of energy consumption, as well as a single or two or morecandidate paths, so that the service user can be informed of details ofthe service. The service user can also select his/her own desired path,based on these details, and give approval to the path. Thesearrangements also contribute to enhancement in the sense of satisfactionof the service user.

Modified Example of Management System

FIG. 15 shows a modified example of the management system 400 shown inFIG. 1. A management system 400 a shown in FIG. 15 includes a firstserver device 400A and a second server device 400B. The first serverdevice 400A operates as a device for managing substitute parkingservice, as one of operations performed by the management system 400.The second server device 400B operates as a device for issuingauthentication information, as one of operations performed by themanagement system 400.

In <4> of FIG. 15, the first server device 400A generates a substitutedriving command to be transmitted to the substitute terminal 200B, suchthat the substitute driving command includes information indicating amethod of accessing the second server device 400B, for example, anaddress of the second server device 400B. The substitute terminal 200Bsends a request for issuance of authentication information, to thesecond server device 400B, using the address of the second server device400B. The second server device 400B issues the authenticationinformation in response to the request for issuance, and sends theinformation to the substitute terminal 200B (<5> in FIG. 15).

According to the modified example of the management system, theoperations of the management system 400 are distributed to the firstserver device 400A and the second server device 400B, without burdeningthe service user and the substitute driver, so that load distributionbetween management of service users and management of authenticationinformation can be achieved. Also, since the user terminal 200A does notaccess the second server device 400B having authentication information,different security levels can be employed for the first server device400A and the second server device 400B. For example, it may beconsidered to set the security level of the first server 400A to belower than that of the second server device 400B, so as to reduceprocessing and time required for communicating with the user terminal200A.

In the illustrated embodiment, the key unit 100 is arranged to behavelike an electronic key, using the substitute terminal 200B. However, thesubstitute parking service according to the above embodiment may beimplemented even when the vehicle of the service user is not installedwith the key unit 100. In this case, the vehicle (physical key) may bedirectly handed over between the service user and the substitute driver.The arrangements according to the embodiment as described above may becombined as appropriate.
